Low-Cost Cell Phone Platform Supports GPRS

Designed for the market’s largest segment, the TrueNTRY X122 low-cost, cellular phone platform for the General Packet Radio Service (GPRS) consists of silicon chips, software (including the company’s protocol stacks and frameworks), and a development kit. The highly integrated platform allows designers to incorporate a wide range of capabilities into entry-level phones, including CD-quality music, camera/camcorder functions, and Internet access, all for a bill of materials cost of less than $30. Built-in features include a speaker amplifier, CD-quality stereo, polyphonic sound synthesizer, USB 2.0 On-the-Go controller with charging, power-management circuits for all phone peripherals, and battery-charging circuits with over-voltage protection. By providing a dedicated applications processor separate from the communications engine, the X122 platform reduces product development costs and boosts overall processing speed. The extra horsepower eases applications software development, test, and verification because it doesn’t impact the core communications engine. It also allows users to receive calls or surf the web while playing music and cuts power consumption, since the applications processor can be powered down the majority of the time that the phone is on. The platform also supports advanced audio processing, such as dynamic noise suppression, echo cancellation, full-duplex speakerphone, and a stereo equalizer. The X122 platform is shipping now.
